In 1499 he became treasurer-general of the domains and finances, reaching the highest peak of the financial bureaucracy, and in 1503, he was knighted by Philip IV of France.
Lauweryn was also councilor and steward of Maximilian of Austria and governor of the children of Philip IV (including Emperor Charles V).
